Disk 35a, 35b, 35c are upper and carry out surface installation by welding.
But when Hall element 8 is installed on housing section 5, if switching point Xcp, Xcn are present in Magnmet rotor portion 2
0 ° of the central location of slewing area Zr be then ideal, but thus Hall element 8 exports output valve H close to the pole N, even if
Far from the pole N, the polarity under the state is also maintained, on the other hand, exports output valve L and close to the pole S, even if far from the pole S,
Also the polarity under the state is maintained.That is, the output Vo of Hall element 8 becomes sluggish output as shown in Figure 5.
Therefore, the selected of the installation site of Hall element 8 can not be installed by simply setting up on the basis of 0 ° of central location
Selected (setting) of the installation site of Hall element 8 becomes important technical factor.Dress is detected in the switching point of present embodiment
It sets in 1, preselects the specific position Xs as optimal installation site, the installation site as Hall element 8.In the situation
Under, in specific position Xs not only comprising relative to magnet part 3 direction of displacement Fm relative position P, also comprising Hall element 8 with
The opposed interval G of magnet part 3.
Firstly, as described above, setting about relative position P, due to that 8 surface of Hall element can be installed on wiring base

The raising of the relevant accuracy of specific position Xs and the reduction of deviation.
In addition, dividing as shown in figure 4, adjusting to use between interval between circuit board 11 and the inner surface 5i of housing section 5
Spacing body 13, it is thus possible to enough settings for easily realizing opposed interval G.In addition, interval adjustment is not special with the material of separator 13
It does not limit, the seal members such as plastic foil, paper membrane can be used.If between circuit board 11 and the inner surface 5i of housing section 5
Between interval adjustment separator 13, then interior table of (setting) circuit board 11 relative to housing section 5 can be easily adjusted
The mounting height of face 5i, it is thus possible to the adjustment for the opposed interval G (specific position Xs) being enough easy to carry out in Hall element 8
(setting).Also, if presence can also be also used as that base will be routed using the interval adjustment separator 13 of double-sided adhesive
Plate 11 is installed on the advantages of installing component of inner surface 5i of housing section 5.
In this way, as specific position Xs, if relative position P and phase comprising the direction of displacement Fm relative to magnet part 3
For the opposed interval G of magnet part 3, then the so-called three-dimensional position that can be realized for Hall element 8 selectes (position setting), because
This, the preferred position being able to carry out for specific position Xs is selected.In addition, 38,39 indicate from Hall element 8 in Fig. 4
